Preliminary
Note: The AP[2:0] in the above description is the instruction bits for gate driver/power supply IC. The
instruction setting in the AP[2:0] must be transferred to the gate driver/power supply IC before an
instruction is executed. For details, see “Gate driver/power supply IC Serial Transfer”.
